HANDHOLE sra norunn Specification of letters Patent, Patented N 6, 1917.

Application filed Septembe 26, 19145. e ia1 No; 863,703.

To all whom it may concern:

Be it known that I, ALEXANDER VVINTON, a citizen of the 'UnitedState's,residing at Lakewood, in the county of Cuyahogaand State of Ohio, haveinvented certain new and useful Improvements in I-Iandhole Structures,of which the following is a specification.

This invention relates generally to machine casings, and particularly tohand hole covers for such casings.

More specifically the invention relates to a hand hole structureutilized more particularly upon the crank casings of engines where oilor other lubricant is being thrown about, the object being to close theopening and prevent the escape of the oil or lubricant to the outside ofthe casing, and it comprises an inwardly extending flange formed aboutthe top and the sides with an outside flange at the bottom adapted toreceive the lower lip of a cover which is set against the side flangesand the top flange and held in position by any suitable means.

The invention may be further briefly summarized as consisting in theconstruction and combination of parts hereinafter set forth in thefollowing description, drawings and claims.

Referring to the drawings, Figure 1 is an elevation of the device withparts broken away; Fig. 2 is a sectional view, and Fig. 3 is a view insection showing a modified form.

In carrying out the invention any preferred form and construction ofmachine or engine casing may be provided with my de vice, but I haveshown one arrangement in the drawings wherein 1 represents a portion ofa crank case or similar machine part having a downwardly extending sidemember 2 provided with an opening 3 which forms the hand hole. Thecasing is pro vided at the sides and top of this on with a continuousflange 4 which is set in from the outer surface of the member 2 to forma shoulder 5. At the bottom of the member 2 it is provided with anupwardly extending lip 6 extending from the shoulder 5 outside acrossthe bottom. This lip is spaced from the lower end of the side portionsof the flange 4, as shown in Fig. 2. and the flanges are broken away atthe bottom flush with the side shoulder portions 5, for a purpose to bedescribed. Engaging the flange 4 is a cover 7 which is adapted to fitdown inside of the lip 6 andengagethe shoulder 5 at the sidesl "Thefront lower edge of the cover is beveled at 8 to fit against the innerwall of the lip 6. Extending along the outside of the lower portion ofthe cover and formed out over the outside of the lip 6 is a flange 9held in place by rivets 10 and furnishing means for limiting thedownward movement of the cover as 1t 15 swung from closed to openpos1t1on, and

also providing afurther means for p'reventing the loss of the lubricant.

In order to hold the cover in place it is provided with a boss 12 boredout to receive the shank 13 of a hand lever 14:. The inner end of thisshank is provided with a latch member 15 adapted to engage on the insideof the flange 4 at the top in a well known manner.

In the modification shown in Fig. 3 the cover 7 is provided with a castflange engaging over the lip 6.

By this arrangement it will be seen that the splash of lubricant withinthe casing is directed by the flange 4 against the cover and toward thecover from whence it drains to the bottom on the inside of the lip 6 andfrom thence back into the case. In this way there is no leakage aboutthe cover.

Having thus described my invention, I claim 1. In a hand hole structure,a casing having a hand hole opening, a cover engaging flange extendinginward from said opening at the sides and top, a lip extending outwardfrom the casing at the bottom and spaced from the cover engaging flan esat their lower portions, and a cover adapted to engage the coverengaging flanges and extend inside of the lip at the bottom whereby anysplash within the casing will be directed against the inner wall of thecover and will be led downward into the casing by the lip.

2. In a hand hole structure, a casing having a hand hole opening, aninwardly extending cover engaging flange extending across the top anddown at the sides and terminating short of the bottom of said opening,an outwardly extending lip spaced from the cover engaging flanges attheir lower ends and extending to a point above the lower ends of saidcover engaging flanges, and a cover adapted to engage the cover engaging flanges and extend inside of the lip at the bottom.

3. In a hand hole structure, a casing having a'hand hole opening, aninwardly extending cover engaging flange extending across the top anddown at the sides and terminating short of the bottom of said opening,an outwardly extending lip spaced from the cover engaging flanges attheir lower ends and extending to a point above the lower ends of saidcover engaging Copies of this patent may be obtained for five centseach, by addressing: the
